HAIRPIN Filed April 4, 1938 INVENTOR ATTORNEYS N. A. JOHNSON 2,148,073

Patented Feb. 21, 1939 UNITED STATES PATENT OFFICE 1 Glaim.

The invention relates to a hairpin and more especially to a locking hairpin.

The primary object of the invention is the provision of a pin of this character, wherein the arms or tines of such pin when engaged in the hair can be latched or locked with each other and in this manner retain the pin securely in the hair on the head of a person so that such pin will be prevented from falling out and also may be concealed by the strands of hair for rendering the same invisible in the wearing thereof.

Another object of the invention is the provision of a pin of this character, wherein the same can be readily handled for the placing thereof in the hair and when so placed for the retention of the dress of the hair will be secure yet it can be readily and easily removed at will.

A further object of the invention is the provision of a pin of this character, wherein the construction thereof is novel and in the wearing of the pin in the hair of a person will be invisible and avoids any discomfort during the wearing of the same.

A still further object of the invention is the provision of a pin of this character, which is extremely simple in its construction, thoroughly reliable and effective in operation, readily and easily handled for application to the hair of a person and removal, strong, durable, and inexpensive to manufacture.

With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a plan view of the pin constructed in accordance with the invention.

Figure 2 is a side edge elevation thereof.

Figure 3 is a sectional view on the line 3-3 of Figure 1.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the hairpin constituting the present invention is formed from a single length of wire A and is bent initially into a substantially U form effecting a double prong frame, the prongs being indicated at 5 and the frame generally at B, respectively, being closed at one end through the medium of a bight 1.

The prongs at the free ends 8 thereof are brought together through the medium of the inbent portions 9 of said prong while intermediate of the frame and in-struck from the said prongs 5 are loop areas l0 approaching each other, these having twists ll reversely disposed to each other and slightly angled reversely to one another laterally to the plane of the frame 6 for the creation of latching keepers or jaws, the wire in its single length being inherently springy and the prongs 5 normally spread relative to each other so that the prongs 5 may be carried into the hair between the strands thereof and by pressing these prongs toward each other the twists ll constituting the latching keepers or jaws will override each other for locking engagement one with the other and in this manner the pin will be locked or made secure in the hair and thus prevented from falling out or disengaging therefrom, the latching keepers constituted by the twists II being shown in Figures 1 to 3 of the drawing in interlocked relation to each other.

The hairpin can be readily removed from the hair on the unlocking or unlatching of the twists II from engagement with each other and the hairpin when worn in the hair and locked with the strands thereof will be invisible and in the use thereof maintains the hair in a dressed condition.

What is claimed is:

A hairpin comprising a frame of a single length of wire having a fold providing spaced inherently springy double prongs, twists in the outer free ends of the prongs and at the intermediate portion of the frame for bringing the free ends of the prongs together and the formation of separated loop areas at opposite sides of the twists intermediate of said frame, and lateral reversely disposed bends in the twists intermediate of the frame for locking engagement with each other and closing the loop areas and also holding together the free ends of said prongs.
